I found this schematic at
http://electronics.stackexchange.com/questions/106862/smps-with-two-outputs-12v-3amax-24v-2amax
It is similar to the wall wart I have.
What I don't understand is how the filter cap can be such a low value. It seems to me that the ripple would exceed the power line peak voltage at 120 volts in. Any thoughts would be appreciated.
Also, does anyone have an LTspice simulation for this or a similar circuit so I can see better what is happening?
edit: Oops. I meant this to be in the chat forum. Can a Mod move it?
